Description

Technical Field

[0001] The utility model belongs to the technical field of filling equipment and relates to a filling equipment for a liquid medium (such as petroleum, alcohol). Background Art

[0002] Liquid medium usually refers to a medium that is liquid at normal temperature and pressure, such as petroleum, water, alcohol, etc. are conventional liquid media. After the liquid medium is produced or collected, it is usually stored in a container such as a storage tank or a storage pool, and then transported by a transfer vehicle when it is needed later. When the liquid medium stored in a container such as a storage tank or a storage pool is transferred to a transfer vehicle, a pipeline is usually set on the container such as the storage tank or the storage pool, and the end of the pipeline is then docked and connected with the filling port on the transfer vehicle through a docking device or a docking device on the filling device, so that the liquid medium is transported to the transfer vehicle with the cooperation of a pump body, a valve, etc. In the prior art, it is more common to set a flexible pipe at the end of the pipeline, and a docking joint is set at the end of the flexible pipe. The staff directly picks up the docking joint and docks and connects it with the filling port on the transfer vehicle. However, the docking is performed manually. First, it requires a lot of manpower to move the docking device, and the labor intensity of the staff is relatively high; second, manual handling will result in low docking efficiency, which affects the filling efficiency of the liquid medium. Therefore, it is necessary to provide a more labor-saving and efficient filling device.

[0003] The utility model patent with application number 201821745316.3 discloses a walking aviation fuel filling equipment, which includes a frame, wheels are installed at the bottom of the frame, and a head is installed at the front of the frame; an oil storage tank is fixed on the frame, and the oil storage tank is respectively connected to the oil delivery pipeline and the oil collection pipeline; the oil delivery pipeline is sequentially installed with an oil delivery pump, an oil delivery filter, an oil delivery flow meter, and an oil delivery joint; the oil collection pipeline is sequentially installed with an oil collection flow meter, an oil collection filter, an oil collection pump, and an oil collection joint. This filling equipment is used for the filling of aviation fuel. On the one hand, it can be freely moved, and the flexibility of use is greatly improved, which solves the problem of inconvenient movement of the filling equipment; on the other hand, the accuracy of aviation fuel filling is greatly improved.

[0004] In the prior art, storage tanks, storage pools and other containers are connected to docking devices through pipelines, and the docking devices at the end of the pipelines are usually fixed in position. The above-mentioned filling device is achieved by installing an oil storage tank, an oil delivery pipeline and an oil return pipeline on a vehicle body, and the vehicle frame together with the oil storage tank, the oil delivery pipeline and the oil return pipeline move as a whole, and the oil delivery pipeline and the oil return pipeline are driven to dock and connect with the corresponding joints on the docking device by moving the vehicle body. However, since the joints in the docking devices connected to the ends of the pipelines of storage tanks, storage pools and other containers are usually fixed, it is very inconvenient to control the joints on the vehicle body and the storage container together with the docking device at the end of the pipeline by the movement of the vehicle body, which greatly affects the efficiency of docking and connection.

DETAILED DESCRIPTION

[0023] Example 1

[0024] This embodiment provides a liquid medium filling device, which is mainly used to fill the liquid medium stored in a storage tank, a storage pool or other container into a storage tank on a transport vehicle through a pipeline and the filling device of this application. It includes: a filling feed pipe 13 and a filling return pipe 14 connected to a container such as a storage tank or a storage pool, the other ends of the filling feed pipe 13 and the filling return pipe 14 are both connected to the filling port on the transport vehicle through a filling valve 8, and the liquid medium stored in the storage tank or storage pool or other container is pumped into the storage tank on the transport vehicle under the action of the pump.

[0025] The filling equipment also includes a frame 1, which can be placed on a load-bearing foundation such as the ground. A y-direction guide rail 2 is arranged on the frame 1 along the y direction, and two groups of longitudinal bases 10 are arranged on the y-direction, one on the left and one on the right (the left and right directions are consistent with the y direction) on the y-direction guide rail 2. Both groups of longitudinal bases 10 can move back and forth along the y-direction on the y-direction guide rail 2 (that is, the two groups of longitudinal bases 10 can move toward or away from each other on the y-direction guide rail 2). A z-direction column 3 is arranged on each group of longitudinal bases 10, and the length direction of the z-direction column 3 is consistent with the z-direction. A z-direction guide rail 4 is arranged on the z-direction column 3, that is, the length direction of the z-direction guide rail 4 is consistent with the z-direction; a z-direction slider 7 is arranged on the z-direction guide rail 4, and the z-direction slider 7 can move along the z-direction on the z-direction guide rail 4, that is, the z-direction slider 7 can move up and down on the z-direction column 3. It also includes two groups of x-direction cross columns 5, one end of each group of x-direction cross columns 5 is connected to the corresponding filling valve 8; each group of x-direction cross columns 5 is provided with an x-direction guide rail 6, the x-direction guide rail 6 is installed on the z-direction slider 7, and the z-direction slider 7 can move along the x-direction on the x-direction guide rail 6 (that is, the x-direction cross column 5 and the x-direction guide rail 6 can move together along the x-direction on the z-direction slider 7).

[0026] When in use, first park the transport vehicle at the designated location, then start the image acquisition device on the filling device to obtain the spatial position of the filling port on the transport vehicle. The filling device drives the filling valve 8 to move in the x direction, y direction and z direction according to the spatial position of the filling port, docks the filling valve 8 with the filling port on the transport vehicle, and finally completes the filling of the liquid medium.

[0027] Example 2

[0028] The filling valve 8 can be fixedly connected to the x-direction horizontal column 5, and the filling valve 8 can also be rotatably installed on the x-direction horizontal column 5.

[0029] To this end, the present embodiment provides a rotatable structure of the filling valve 8. That is, a pneumatic pump 9 is provided at the end of each group of x-axis horizontal columns 5, and the output shaft of the pneumatic pump 9 is connected to the corresponding filling valve 8; the pneumatic pump 9 is used because when the filling equipment is in use, some use situations require explosion-proof requirements. Under the action of the pneumatic pump 9, the filling valve 8 can be driven to rotate with the z-axis as the axis. Since the filling valve rotates with the z-axis as the axis, the connection method between the top of the filling valve 8 and the filling feed pipe 13 and the filling return pipe 14 can adopt the existing rotatable connection method.

[0030] Example 3

[0031] In the prior art, after the docking is completed, the staff manually opens the valve on the filling valve 8 to fill the tank. However, this greatly increases the labor intensity of the staff and greatly reduces the filling efficiency.

[0032] To this end, based on the above embodiment, a filling valve 8 which can be opened and closed automatically is provided.

[0033] The filling valve 8 comprises an L-shaped main valve body 81, the upper part of which is connected to the filling feed pipe 13 or the filling return pipe 14. The other end of the main valve body 81 is connected to a valve 86, which can be opened or closed by rotating a valve plate in the valve 86.

[0034] A valve driving cylinder 82 is provided on the outer surface of the main valve body 81. The valve driving cylinder 82 is used because the filling device needs to be explosion-proof in some use situations. The output end of the valve driving cylinder 82 is connected to a rack 83, which can move along the axis of the valve 86. A gear 84 is provided on the valve, which can rotate coaxially with the valve plate of the valve 86, and the gear 84 is meshed with the rack 83.

[0035] In this filling valve 8, the rack 83 can be driven to move by the valve driving cylinder 82, and the moving rack 83 will drive the gear 84 and the valve plate coaxial with the gear 84 to rotate together, thereby realizing the opening or closing of the filling valve 8.

[0036] Example 4

[0037] Since the filling valve 8 needs to move in space in the x, y, and z directions during docking, in order to avoid the filling valve 8 from colliding with the filling port on the transport vehicle during the movement, a certain gap needs to be reserved between the filling valve 8 and the filling port after the filling valve 8 has completed its spatial movement. This requires that after the filling valve reaches a certain specified position, it needs to move a small range in the direction close to the filling port and fasten the filling valve to the filling port.

[0038] Therefore, based on the above embodiment, the structure of the filling valve 8 is further refined in this embodiment.

[0039] That is, the other end of the main valve body 81 is connected to the valve 86 via the telescopic hose 87 , and the distance between the main valve body 81 and the valve 86 can be adjusted via the telescopic hose 87 .

[0040] A snap-fit ​​drive cylinder 88 is also provided on the main valve body 81. The snap-fit ​​drive cylinder 88 is used because the filling device needs to be explosion-proof in some use situations. The output end of the snap-fit ​​drive cylinder 88 is connected to a snap-fit ​​piece 89 through a connecting rod mechanism 85. The entire filling valve 8 can be matched with the snap-fit ​​piece on the filling port through the snap-fit ​​piece 89 and snap-fit.

[0041] In the structure of the filling valve 8, since the other end of the main valve body 81 is provided with a valve 86, and there are also corresponding fastening parts 89 and a connecting rod mechanism 85, which have a certain weight, it is necessary to consider that the valve 86 will not fall off during the process of connecting the main valve body 81 and the valve 86 through the telescopic hose 87. Therefore, the problem can be solved by adjusting the material of the telescopic hose 87, the rigidity of the connecting rod mechanism 85, etc., which can directly adopt the relevant existing technology and existing design without creative labor.

[0042] In addition, regarding the connecting rod mechanism 85, the connecting rod mechanism 85 in the prior art can be used, as long as the valve 86 can be driven by the cylinder to move along the axial direction of the valve 86, no creative work is required. In addition, regarding the specific structure of the fastening member 89, this is the prior art, and most of the existing filling equipment has the fastening member 89, so no creative work is required.

[0043] When in use, wait for the spatial position of the filling port on the transport vehicle to be obtained (x 1 ,y 1 、z 1 ), the filling device first controls the filling valve 8 to the specified position (x 2 ,y 1 、z 1), and then the driving cylinder 88 is engaged to drive the connecting rod mechanism 85 to move, driving the valve 86 to move along the x direction. During the movement of the valve 86, the telescopic hose 87 is stretched or compressed, and finally the valve 86 is connected to the filling port, and the fastening part 89 is fastened and tightened with the fastening part on the transport vehicle.
